But here's the thing, even as a whole, the FGC is somewhat splintered between games and different subtypes of FGs. Why is this important? Because Esports aren't going to take on ALL FGs, just the most popular ones.
As of now, that's AEv'12 and UMvC3...but considering the unlikelyhood of getting those due to licensing issues, then we move on. eSports are also EXTREMELY unlikely to pick up any 2D games tbqh, so that takes out KOF and Blazblue. That pretty much leaves the 3D Fighters, which is no surprise as the only two FGs supported by eSports were 3D Fighters. Which means, more than likely Soul Caliber V and Tekken Tag 2 as the only candidates.
TBQH, anyone who doesn't play 3D Fighters should not get involved in this unless Capcom actually decides to deal with the licensing, which I doubt will happen. I don't play them, so I personally should not have an opinion and rightfully so.
